The European Free Trade Association (EFTA) is a trade bloc created on January 4,1960 by the Stockholm Convention as an alternative to the European Economic Community (1957) with Austria, Denmark, Great Britain, Norway, Portugal, Sweden and Switzerland as members. It came into being in June 1960. In 1961 Finland joined, Iceland in 1970 and Liechtenstein in 1991.

The EFTA is a group of countries that have chosen not to join the European Union.

Its objective is to promote the economic expansion and financial stability of all its members.

Great Britain and Denmark left the EFTA in 1973 choosing instead to join the CEE. Portugal followed in 1986, Austria, Sweden and Finland in 1995. Since then the EFTA has become a select group of countries. Two Alpine countries remain: Liechtenstein and Switzerland and two Nordic countries, Norway and Iceland.

With this strategy, belonging to the EFTA, Spain cannot boycott the presence of Catalonia. At the same time, EFTA belongs to the European Economic Area.

WHAT IS THE EUROPEAN ECONOMIC AREA?

The European Economic Area (EEA) was founded on January 1, 1994, through an agreement between countries in the European Union (EU) and European Free Trade Association (EFTA). Its creation allowed EFTA countries to participate in the internal market of the European Union without having to join the EU.

The members of the Association include the 27 member countries of the EU, and the following EFTA members: Iceland, Liechtenstein and Norway.

In a national referendum on December 6, 1992, Switzerland, as an EFTA member, refused to join the European Economic Area, despite the fact that the majority of votes were in favor of joining the EEA. Currently, Switzerland's relations with the EU are governed by a set of bilateral treaties as a member of the Schengen Agreement.

Madrid and Catalonia - Are the tensions beginning to thaw?

Catalonia has been in a state of crisis. The region of Catalonia has locked horns with Madrid, and they have been dueling ever since the announcement of the referendum.

In many ways, Catalonia appeared to be falling into an abyss of no return.

Careful observation, however, will reveal a number of updates that suggest that the situation is thawing.

On Friday, Spain's senior governmental representative in Catalonia Enric Millo asked forgiveness for the brutal police violence during the referendum. A judge from Barcelona has opened an investigation into the events, and the Barcelona City Council condemned the violence of the state. They also demanded the resignation of Mariano Rajoy, who will be tried in Lleida, Mataró, Amposta, Mollet, Puigcerdà, Tremp and Tarragona.

Proceedings to investigate the actions of the Spanish police forces will also be carried out. The vast majority of police installed in Reus, Lleida and in other towns have been transferred to Huesca. After a concerning lack of European support, yesterday, an important newspaper in Germany, "Frankfurter Allgemeine", dedicated its front cover to secession, and "The Economist" printed that a referendum is essential to solve the Catalan case.

So, what has catalyzed all of these changes? Just a few days ago Carles Puigdemont asked for the immediate transfer of police from Catalonia, in order to initiate mediation. On Friday, Switzerland offered to mediate between Spain and Catalonia, hours after this announcement Puigdemont said the announcement of independence will occur on Tuesday rather than Monday, allowing more time for preparation.

On top of this, the arrested activists and police chiefs, Trapero, Sánchez and Cuixart have been allowed to leave the National Court without precautionary measures.

This defrosting effect will hopefully continue.Democratic dialogue and the healing of past wounds will maybe save Spain from a dirty future of political unrest, internal strife and perhaps even another civil war.
